Have you ever seen a video image when there is too much light in one area? Imagine a car at night with its headlights shining right at you. While you can clearly see very bright glares from the headlights, you usually can't see any detail of the car itself. CNB's Blue-i is a package of several technologies to control light: the Eclipse function makes the headlights into dark circles, and allows very clear details of the rest of the picture to be seen. Extra Wide Dynamic Range (XWDR) provides balanced pictures when the subject is backlit. Its 3DNR function balances the light and dark areas of the picture to render more detail than possible with normal cameras. There's an IR Cut filter which is automatically removed at night to allow more light to enter the lens when it's dark. The Stabilizer removes any swaying effect from wind, traffic, etc. The vari-focal lens allows you to focus on exactly the areas of the scene you need. Built-in long-range (260', 80m) infrared (IR) LEDs illuminate the field of view for taking video even in total darkness. The mounting bracket has an internal passage for cable management, protecting the cables from vandals. The housing is built to the demanding IP67 weatherproof standard, and has a built-in heater and fan to eliminate condensation.
